+ <background>
+ <p>
+ Perl is a stable, cross-platform programming language created by
+ Larry Wall. The perl-suid wrapper allows the use of setuid perl
+ scripts, i.e. user-callable Perl scripts which have elevated
+ privileges. This function is enabled only if you have the perlsuid USE
+ flag set.
+ </p>
+ </background>
+ <description>
+ <p>
+ perl-suid scripts honor the PERLIO_DEBUG environment variable and
+ write to that file with elevated privileges (CAN-2005-0155).
+ Furthermore, calling a perl-suid script with a very long path while
+ PERLIO_DEBUG is set could trigger a buffer overflow (CAN-2005-0156).
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ A local attacker could set the PERLIO_DEBUG environment variable
+ and call existing perl-suid scripts, resulting in file overwriting and
+ potentially the execution of arbitrary code with root privileges.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ You are not vulnerable if you do not have the perlsuid USE flag
+ set or do not use perl-suid scripts.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Perl users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose dev-lang/perl</code>
+ </resolution>
